Buy KPV for Research: 2 Vendors Compared (Prices, COAs)

Checked, not rated · Updated 3 October 2026

KPV is not approved by FDA for human use, and it is sold in the US labelled for research use only. 2 of the 3 vendors I check sell it online (Next Level Pharm and BioEdge Research Labs), from $48.99 for a 10 mg vial as of 3 October 2026.

The table compares vendors on FDA record, testing lab, batch COAs and price. Before buying from anyone, run my vendor checklist.

KPV vendors compared

The checklist results come from my review of each vendor and cover the whole store. A vendor can publish COAs for some products and not others. The featured vendor is pinned first; the order is not a ranking.

KPV capsules

Capsules are taken by mouth and are a different product from the vial. The vial's COA does not cover them, so ask for a COA for the capsule batch. They carry the same research-use-only label.

What a KPV COA should show

A certificate of analysis (COA) is the lab report for one batch. For KPV, check these:

  • Identity by mass spectrometry, with the expected and the measured mass side by side. For KPV, expect about 342.43 Da (C16H30N4O4); the sequence is 3 amino acids, KPV.
  • FDA found a compounding nomination whose certificate of analysis named one form of KPV (free base or acetate) while its formula matched the other. Check that the form named on the COA and the mass reported agree.
  • Purity by HPLC for this batch, shown as a chromatogram as well as a percentage.
  • A lot number that matches your vial or pack, the test date and the lab's name, so you can confirm the certificate on the lab's own site.

A purity figure does not cover sterility or bacterial endotoxins; a COA covers those only if it reports separate tests for them. Line by line: how to read a peptide COA.

Red flags when buying KPV

  • Capsules or creams sold with gut or skin treatment claims. FDA found no study in which KPV was given to a person for anything.
  • No certificate of analysis for the batch you will receive, or one without a lot number or a named lab.
  • Dosing instructions or treatment claims for people on the product page.
  • An FDA warning letter naming the seller. Search fda.gov before you pay.
  • No way to pay with buyer protection, such as a credit card.

Common questions

Where can I buy KPV?

Online, from research vendors that label it for laboratory use only. I list 2 checked vendors: Next Level Pharm and BioEdge Research Labs, from $48.99 for a 10 mg vial as of 3 October 2026. Before you pay, confirm the batch COA on the testing lab's own site.

Is KPV for sale legally?

KPV is sold in the US labelled for laboratory research use only. It is not approved by FDA for human use, and it cannot lawfully be marketed as a supplement or a medicine. On 23 July 2026 the Pharmacy Compounding Advisory Committee voted 8-6 to recommend adding it; as of 3 October 2026 no Federal Register rule had done so. This is general information, not legal advice.

Do I need a prescription for KPV?

No US-approved KPV product exists for a doctor to prescribe. Research vendors sell it without a prescription, labelled for laboratory use only. KPV is not on the 503A Bulks List, so it is not currently eligible for lawful 503A compounding. FDA staff proposed not adding it.

How much does KPV cost?

On the vendors' own product pages: Next Level Pharm, 10 mg vial, $48.99 (as of 3 October 2026); BioEdge Research Labs, 10 mg vial, $49.00 (as of 3 October 2026). Prices change often, so check the product page before you rely on one.

How do I know if KPV is real?

Only a lab test can tell you. Ask for the certificate of analysis (COA) for your batch, and confirm it on the testing lab's own site. The mass spectrometry result should match the expected mass of KPV, about 342.43 daltons (C16H30N4O4). A vendor's COAs for other products say nothing about this one, so check that the certificate names KPV and your lot number.

Who sells the best KPV?

I don't rank vendors, so I don't name a best one. Compare what each lets you check: a named testing lab, a COA for your lot that the lab confirms on its own site, and no FDA warning letter. The table shows my checklist result for each vendor. A vendor that passes every check can still ship a bad batch.
